First of all I would like to say that the ROKU OS has lots of potential to be best. Got a lot of experience with TV that has FireOS, Android TV and Google OS. Their TV settings is perfect. especially when controlling (Motion.) If only ROKU could create a slider for motion smoothness and slider for action clarity. Specifically in TCL 6 series. or Any ROKU TV that would be awesome. As for now we cannot calibrate motion to our user specifications. Only settings that there is are (Low, Medium and High) Its like saying 25%, 50% and 100%.) If we could really make it as slider like to Android TV, FIRE OS tv motion settings.) That would be great. Controlling motion and clarity is one of the most important in the tv settings especially if the TV has the ability to remove judder. Hope ROKU OS will update this.
